HeCv," emergence of cotton flea hopoer is reported from Texas.

Pink: bollvorm emergence began the third veelk in .:x'bruary in the
State of Durango, "*exico. This insect has thus far carried over in rather
lar e numbers in the soil in the vicinity of Presidio, Tex. All cotton
fields examined in Puerto Rico vere found to be lightlr infested with this
pest.

Fall cankerworm was generally prevalent throughout New "nglandi and
the Middle Atlantic States, and spring; cancrworm was active during the
latter half of the month from Iowa and "-issouri southward to Kansas and
3:Iliho 1-n.

Observations made this s-ring indicate that the screw worm fly was
not able to pass the winter north of the southern two-thirds of Florida
and the southern third of Texas.

GENERAL FSED3RS


'.THITE GTRUBJ3S (r-hyl ophaga s-r.)

Louisiana. 3. A. Osterberger (March 'l): The first June bug flight at
3aton Rouwe of this season was on the night of 'I,*rch 8. It consisted
of P. calceat' Lec. and. L. con .rua Lec. Only a few, have been noticed
in flight since tha.t ti-ne.
Xansas. H. R. Bryson (larch ?3): --:cPvations reveal the fact that white
grubs are not so abundant at "lanhattan as 2ig~ht be expected fol losing
the beetle year. A number of dead grubs have been found v-ithin, "the
first 6 inches of soil and a-7peatr to have been leilled by lo," tem-rra-
tures.

Texas. T. L. Thomas (March 28): .7_ calceata is active at -oresent; on
March 23,M2 -ere collected at light. P. crassissima 'Blanch., P.
hirtiventris Horn, P. pre.etermissa iorn, F. rubiginosa Lec., and I.
orofunda Blanch.are also active.

J. AZu's 32TL3 (Popilli. japonica :erm.

Pennsylvania. R. ". Baker ('.rch 24): ",e -re rlannin:- to d, some soil-
treatment "' or in the city of ::rie a,;ain this yecpr with the coonera-
tion of the Federal Government, starting. Arril 1'. In this area we
are tramping fer'er beetles each year out these fev are s-reading over
a gradually widening ter-ritory r-ithin the city lim-its.

CUT"-.O"S (iToctuidae)

Colorado. G. :`. Li't (March 17): Dur'in,; the last fe" days the r.r-i
cutwvorm (Chorizagrotis auxiliaris Grote) has been rc-orted a6
dam-aging wheat in Boulder, -7eld, and Larimner Counties.

Arizona. C. D. Lebert (la.rch 24): Several s-ecies of cut''orms are
giving trouble to lettuce and melon grovers. Some da-na:e has occurred
also on residential floer beds. The 'oredoninant species is Agrotis
ypsilon aott.

O::'C" '_ UTr:2-'LY (Danaus -nenip<- Hbqn.)

2lorida. H. T. ?ernald ('Aarch 21): The monarchs have entirely disa-riear-
ed at Orlando. They have probably laid their eggs and died and there
should be nearly grov;n larvae or 'pwoae now, as the fresh adults
normally awoear about Arril 1.

C0O"'01 22D SFIPIR (Tetrenybhus telarius L.)

"issi ssi-'--i. C. L.'le and assistants ('r2ch 35): Heavy infestation of
red s--ider on lilies in a eenHoue at Moss Point was observed on
M"rch 17. The -est.is fairly abundant on arborvwitae-AinLincoln and
Pi3-e Counties and'is present on' Canellija &j:onica-at Poolarville
and Picayuie. A rather heavy infestation vas noticed-in a satsuma
orchard in Harrison County on Marc i l4.-"

Louisiana. B. A. 0sterber-er (March ?l): .The common red sAiier.is
numerous on azalea -and .rborvitae 4
Missouri. L. Hase an (iMarch 24): Tle red spider was a very serious
7est in a nu mbcr of central- and northvestern-Missouri orchards
and a few snuthvestern-'Missouri orchards during; the dry July of 1935.
Unbelievable niunbers vent into resting qr hioern ting conditions in

C7I11C. BUG (Bli,.quy lmco'teru Sey) :

General. F. N. Annand (,'arch W1): Freliminary reports: on -nortality o:i
chinch bugs in the seriously in'feted area of the Corn 3elt States
indicate that average mortalitiess as hi.6h as -.50 percent occur in.
certain counties in Iowa, Illinois, and Indiana, Mortality is
considerably lover in 71issouri, Xansas, and,07:lahlona. :]ven with the
mortality indicated at present, there are sufficient bu's to cause
serious darade should spring weather be favorIble.

Indiana. C. Bentdn ('-.rch.h20): ..The findinE- of forty additional samples
of bunch jrasse, in Timec-; oe County.on Februery 27 and M7arch 16
substantiates lecst 'nonth's re-ort of about 50 percent -nortality of
hibernating chinch bugs.

Illinois. 'J. F. Flint (March 30): Iecent general surveys of the chinch
bug infested area have shov-n that the bugs canmF through the winter
v ith mortality of approximately 20 to 25 noercent. Our examinations
to date indicate that there eo about 80 ocrcent as Tiany bugs nov in
hibernation as there were in the s ooing of 1"'74. There are enough
bugs to cause serious danaie should the weather of the late s-ring
be dry.
Correction.-Chinch bug mortality in Indiana as reported in the Insect Pest
Survey Bulletin dated March 1, 1936, p.5,should read"from 19 to 98 percent.






-31-


Iowa. H. E. Jaques (March 25): Chinch bugs are coming out of hibernation
in large numbers in southeastern Iowa.

'issouri. L. Haseman (March 24): ]-Totwithstanding the severe cold, the
chinch bugs have wintered -ith only 10 to 20 percent mortality in
the'highest mortality counts. Some of our counts in the recent surveyr
shoV fro-i 500 to 1,000 bugs F er bunch grass clmon apmroximtely 3
inches in diameter, but generally the numbers of bugs ars fex-er than
they vere a year ago. Over mo--t of the corn-gro-ing section of the
State there are enough hibernatin: bugs to cause serious damage
should v e ha-ve a dry spring and summer.

Kansas. H. 1. 3ryson (March 25): -To flight of chinch bugs has been ob-
served. Counts reveal the fact thpt the winter survival was high.
The number in hibernation shoved moderate abundance.

GCL:T 3UG (Toxoptera 'rLrninun rLond.)

Kansas. H. R. ]3 "son ("srch ?5): l-o green bu,.s -ound. by E. Gi. Celly in
southern Kansas.

Oklahoma. C. F. Stiles ('"rch 24): The fist re-ort of green bugs reached
me on "arch 21 from Comanche County. A fev spots of injury are shot-
ing u-i in volunteer oats that were not killed during the winter.

TH7SSIAYN iLY (F.. 'to.haj destructor Say)

Missouri. L. Hase-nan (k-arch 241): The hessian fly situation, as sho'n by
a State survey that has just been cow--leted, indicates that froa
the tier of counties along .the Missouri -aiver south the infestation is
serious, -ractically all of the early seeded fields shoring from 5
to 90 -oercent of the plants infested, and, in many cases, "-ith fields
seeded on the previously announced saf.e-see.:11i date shoring 10
percent or nore of the -olants infested. .any ox the worst infested
fields have already been reseeded to oats and other fields vill
undoubtedly be aba.doned later. In central 'issouri we find consider-
able numbers of dead "flaxseeds", but the mortality seemin-gly is not
due to narasitization. 7e do not believe, however, that the viuter,
vith the `fine blanket of snov, is responsible .or their death.

Kansas. T. R. Bryson (March 26): E. G. Kelly reports hessian fly
abundant rith considerable damage to v-heat in the 25 counties in
southern and eastern Xansas.

Oklahoma. C. . Stiles ("arch 24): The center of infestation seems to be
around Billings, on the :Toble and Garfield County line, in the heart
of our best v'.et-groving section. Sone fields last fall had 60
percent infestation. Scattering reports have also been received from
nearby counties stating that hessian flies are vorse than they have
been for a number of years.

CO&ZT

COR1I SAP2 "701M (Heliothiis obsoleta Qab.)

Texas. -2. L. Tho-as and assistants (March 18): -xaminations for e-'cs or
adults of the cotton boll rorm vere made beginning '"arch 12 in the
un-o-er coastal section of Texas, but none reie found until the 23d.
On that date 400 -lants of alfalfa e;-:ani.ied at three locations
yielded 51 egjs; 4 adults were ta:en from 400 sw'e--es made on the same
date; 15 eg- s and 2 larvae were found on ?0 stalks of corn 6 inches
hiJi. :Tcar College Station on lfarch 10, 2 e-,s vere found out of
about 1,300 alfalfa -slants ex-ni:.ed; on "arch 12, 500 plants were
ex.-nined and 1 e-;g found; and 8 e.:';js v e3e found on 3,0 alfalfa r0lants
exa-nined on March 23 and 24.

A. Glic:! (March 17): Corn ecr worn is quite abundant now
roland Brovwnsville, having an-neared on '.vrch 15, both in the field and
at ligts. '.;e are mal:ing infestation counts of lprvpl da-nage to young
corn.

EUROP.Ai: CORI' 3OR: (ryrausta nubilalis Hbn.)

Rhode Island. A. L. Stene ('larch 27): The corn borer is not unusually
abundant, but little mortality is shoring u-w amon: those that went
into winter quarters last fall.

ALFAA L

AFALiFA '7.7VIL (H.y-era nostica Gyll.)

California. A. E. Michelbacher ("iarch 2'0): The alfalfa weevil is doing'
very little dan-je. Injury is noticeable in only one field, located
at Irvington, vhich is ready to be harvested, and it is expected that
danac;e will cease as soon as it is cut. Over much of the San Fran-
cisco district and the San Joaquin Valley the alfalfa is reachiCj
maturity end harvest has already started in a number of fields. In
the San Francisco Bay area -narcsitization by 3athy.plectes curculionisTiTs.
continues to be heavy, but no reports lhter than 'larch 3 are included
because the rearing records beyond this date are not yet completed.
Very fev of the Bathymlectes reared since February 26 are of the
ovcrintering for-n.

APPL2 APHIDS (A6h iidae)

Vermont. H. L. bailey (?"'arch 25): g .gs -of the reen anrle a-ohid (Aohi s
'oomi DeGr.) .re moderately abund.-nt at Shelburne and Chrlotte, in
Chittenden County.

Connecticut. P. Gar-ran ("arch 23): .*--'.id eggs are abundant in nea-rly
every orchard visited in :eTo Haven County. !"se hatched so far" in
the laboratory a'e of the greenn a -le aphid.

.o% Yor':. P. J. Farrott (Merch 19): A-Aid e,-,s are -lentiful in
7:estern Te- Yor'h.

Tennsylvania. H. E. Ho&dl:Iss (M'arch 24): A-ihid er-;s are -ene rally ,'-'bun-
dant throughout the State.

VirTinia. .. J. Schoene ('arch >-5): Tie ne'!y hatched a--le a-hids ve: e
found on a7--[le buds in the -7oano:e section by "'a-ch 14 and in the
Crozet section by March 13. It ameers no," fron the few observations
made that a heavy infestation of the rosy aphid (.Turc-hi. roses
3aklcer) will occur in Virginia orchards this Thr. The insects vere
observed on the folia.'e in large numbers lest fall, also a fer have
been hatched prematurely by ta:in5 the egs in the house.

..est Virginia. L. M. Feeirs ('larch 28): I have :e--orts from-n several
sections, notably the eastern Ta:nhandle and `'onoigalia County, that
anhid e.gs are extre-mely abundant on apple. -g.s hatched in the
laboratory -orove to be about 40 -ercent green a-hid (A, nooi) and 30
percent rosy a,.id (A. roseus).

".ichigan. Ray Hutson ('March 235): Anhid eis -re very -Qlentiful through-
out the fruit belt along Lak-e ichigan.

Iova. H. 2. Jaques (.Tarch 25): So-ae a-yle trecs shove p rather heavy in-
festation of aphid eggs.

Utah. C. J. Sorenson (March 19): 2ggs of the green anple aphid and. the
rosy a-pile aphid are co-ion in an-ole orchards in 3oxelder County.

Oregon. B. G. Thompson (M arch 17): Ros:" a-'le aohid at :ionroe, the first
bei.;.i found on March 17.

LEAFHOPP-MS (Erythroneura spp.)

Missouri. L. Haseman (March 24): The two common species of anle leaf-
ho-o-pers, the red-spotted (E. maculata Gill.) and the red-striped
(3. obliqua Say) have survived the severe winter, though recent counts
indicate between 40 and 50 percent mortality in leaf and grass cover-
age in the orchards at Columbia. These leafhon-oers for the oast two
seasons have been very serious and we are ho: ing that the winter
mortality may somewhat lighten uo their numbers for the coming summer.

SAN JOSE SCALE (As-oidiotus nerniciosus Comst.)

New Yorl:. F. J. Parrott (March 19): San Jose scale is common in many
poorly sprayed and neglected orchards in western ITew York.

Virginia. 17. J. Schoene (' arch 25): Examinations at various points in
the State indicate that more San Jose scale is n-resent than for several
years.

Georgia. 0. I. Snapi (March 3): Thirty-three thousand scales from
uns-nrayed peach trees at Fort Valley were counted at intervals during
the winter to determine the percentage of live scale in an orchard
being used for experiments. The results are given in the following
table.


Date : Dead scales : Living scales

: Number : Kunber : Percent
January 13 to 21 ..... 7,432 : 23,168 : 75.71
February 13 ..........: 241 359 : 59.83
March 3 .............. :704 1,096 : 60.89


Live scale on unsnrayed reach trees at Fort Valley decreased 15 percent
between January 13 and March 3. This is believed to be due chiefly
to the twice-stabbed ladybeetle (Chilocorus bivulnerus Muls.), rather
than to cold weather, as v'e have shown heretofore that a minimum tem-
perature of 16 F. will not kill the San Jose scale on 'each trees in
Georgjia. The minimum temperature recorded at Fort Valley during the
winter was 15; however, this has been one of the coldest winters on
record, not because of the unusually low te-mperatures but owing to a
number of long periods with daily minimu-ns below 320.

C. H. Alden ('arch 23): There is good control of the scale in
well-sprayed peach and apnle orchards at Cornelia, but from moderate
to severe infestations have been observed in unsprayed or poorly
sprayed orchards.

Ohio. T. H. Parks (March 25): An examination made March 25 showed a high
mortality at Columbus. winterr temperature reached -17 F., and only a
very few of the insects survived.












J. S. Houser (March 38): A mortality record was made of scale
taken from vigorous a-o-'le wood moderately infested at Sandusky. Of
500 individuals in the overwintering stage examined only 9 -ercent
'rr,* alive. The condition of the scale varied greatly from twig to
twig. On one lot of twigs only 1 -ercent of the scale was alive,
whereas on another lot 23 percent were alive. The minimum temera-
ture in this locality as reported by Mr. G. A. Runner was -12 F.

Illinois. T7. P. Flint (M'arch 20): The weather of the oast winter caused
a very high -ortality of San Jose scale. South of Carbondale from
10 to 20 percent of the scale is still alive. North of Carbondale
the k'.ill was very high on the vest side of the State, being froa 97
to 98 percent except on parts of the trees protected by snow; it was
slightly less on the east side. In the area north from St. Louis
more than 99 percent of the scale was killed.

Michigan. Bay Hutson (March 35): San Jose scale is very spotted in the
fruit districts along Lake Michigan. There are places where trees
not sprayed regularly for the scale show live scales.

Alabama. J. M. Robinson (M'arch 21): San Jose scale is moderately
abundant on peach trees.

Missouri. L. Haseman (Matrch 24): This -oest during the -oast sumner built
up rapidly in many sections of the State, encrusting many youn:. fruit
trees. The subzero temperatures and the -orolonged cold have been
very beneficial,in kdlling off this -est. Recent counts from the
latitude of Columbia and to the north indicate that on the most
ex-osed trees above the snow line the mortality is nearly 100 percent,
with some counts taken on sheltered places indicating sufficient carry-
over to enable the nest to build up a-rain this summer if conditions
favor it. Much of the dormant spraying planned for northern Missouri
rill probably not be done in vie'. of the effective kill by the cold
weather.

Oklahoma. C. F. Stiles (Varch 24): A few of the orchard men report that
the severe winter has killed a large percentage of the scale in the
vicinity of Ok-lahoma City.

CODLING MOTH (Car-oca-sa nomonella L.)

Georgia. C. H. Alden (March 23): The codling moth is still in hiberna-
tion at Cornelia; no pupation to date,

Ohio. T. H. Farks (March 25): An examination made yesterday shows that
most of the overwintering codling roth larvae at Columbus vwere killed
by the lov' winter temperature. The lowest reached was 17 below zero.
Below-zero temperatures were recorded during 10 days.

LIBRARY
kT&iTE PLANT BOARD












iissouri. L. Haseman (Mh.rch %): *he number of codlii[ moth larvae oin
into hibernation lest fall vas the smallest for many -ears and, rith
te-q-rratures ran:)in from nearly ?,0o belov in the northern mart of the
State to from 10lto 1?o or 150 below in 0--t-ol and southern 'issouri,
re have had a considerable 'ill of those hibernating above the sriov'
line. Recent exar:,i,.tinns, ho,-ever, short t1hrt in central "issouri the
winter mortality has not been 100' --'cCnt by any means, for le are
finding considerable numbers of live larvae on the tree trunk's aboove
the snov line.

Colorado. G. M. List ('Mlarch 17): Frelilinary examinations at sort Collins
indicate about an average ,-inter mortality of codling -Ioth larvae.
L7ith the large .o-omlation that rent into hibernation in most sections of
the State, there rill be a heavy flight of'moths if the weather continues
favorable.

Utah. C. J. Sorenson ('t.rch 19): A high percentage of codling --oth larvae
have survived the vinter, judAging from rather limited investigations in
Box 2lder County.

Sa3TIa: T.' CAT3Rr-ILhL'-2 ('lco-.,-a arnericana .ab.

Kewv York: and Delaware. E. T. 2elt ('larch 24): "' masses of the a-mle
tent cater-illar are very abundant in many localities, although indica-
tions are that the outbreak: will be iesq general l than that of last
year. ,fny egg masses are being collected by Boy Scouts and school
children in various localities in T17er Yor'- State and Nerw Linland. The
egg -iasses a?-:estr to be less abundant in eastern len-Tslvania and in
the vicinity of Y'ilmington, Del.

Vermont. H. L. Bailey ("arch 35): Tent caternilln.r egg itr.sses are
moderately abundant in the southern art of the State; less so in
northern sections.

Connecticut. '. E. 3ritton ('7orch 23): 2 g clusters are very a-bundant in
some localities on wild cherry and an-plI throughout the State; in other
localities they are less 'revalent than in 19&5.

Fennsylvania. H. Hodg'fAss ("arch 24): There is a rather general abimndnce
of the e gs of the eastern tent cater-oillar.

Arhnsas. "7. J. 3aerg ('>rch 17): About one-third of the egg masses are
hatching at Fayettevile today, the others hatched earlier; hatching
probably began about !.arch 13. .'gg masses are moderately com-mon, but
not as abundant as they have been in recent years.

Xansas. H. 3ryrson ("arch 26): Flat-headed a-nle tree borers are very
abundant in ao-jos end other trees throughout the State. InfegtPtion
is due to the weakened conditions of the trees, resulting from
drought and red sAider or aphid injury during thle past 3 years.

TLOTER TMFIPS (Fankliniella spp.)

the infestation has been quite heavy on the ac-acia trees but the leaf-
honopers are not very abunCant nov. This leaho,'^-er was first collected
on silver wvattle growVing in Altade-ia in 'Zoveiober 1932. The infestation
at that ti-ne was light but evidences of injury indicated that the
leafio-Tpers had at one time been very nu-iernus. The orange trees
adjacent to the two silver wattles at San Dimps show ty-oical leafhopper
da-na.;-e and the extent of damage decreases, es-ecially on the fruit

screw worm fly (C. amnericana) vas a'le to over-inter only as far north
as Dixie, Gilchrist, Alachua -utnam, and 2lagler Counties in north-
eastern Florida. A few infestations of ani-ials have occurred in counties
along the Georgia-Florida line, indicating th.t there has already been some
migration of the pest from the area here it overwintered. In Texas the
fly overwintered only as far north as Val Verde, Xinney, Maverick,
Uvalde, Frio, Atacosa,. Wilson., -Tnzales, ,*.rton, and 3orazoria Counties.
Spring outbreaks have been reported from Uvalde end Val Verde Counties.
